                This is the abstract base class for all graphical objects.Classes inheriting from GraphObject include:<a href="../symbols/Shape.html" class="linkConstructor">Shape</a>, <a href="../symbols/TextBlock.html" class="linkConstructor">TextBlock</a>, <a href="../symbols/Picture.html" class="linkConstructor">Picture</a>, and <a href="../symbols/Panel.html" class="linkConstructor">Panel</a>.From the Panel class the <a href="../symbols/Part.html" class="linkConstructor">Part</a> class is derived, from which the<a href="../symbols/Node.html" class="linkConstructor">Node</a> and <a href="../symbols/Link.html" class="linkConstructor">Link</a> classes derive.<p>It is very common to make use of the static function <a href="../symbols/GraphObject.html#.make" class="linkStatic">GraphObject.make</a> in order to build upa visual tree of GraphObjects.  You can see many examples of this throughout theIntroduction, starting at <a href="../../intro/buildingObjects.html">Building Objects</a>,and the Samples, starting with <a href="../../samples/minimal.html">Minimal Sample</a>.<p>Since GraphObject is an abstract class, programmers do not create GraphObjects themselves,but this class defines many properties used by all kinds of GraphObjects.<p>The only visual properties on GraphObject are <a href="../symbols/GraphObject.html#background" class="linkProperty">background</a> and <a href="../symbols/GraphObject.html#areaBackground" class="linkProperty">areaBackground</a>.However one can control whether the GraphObject is drawn at all by setting <a href="../symbols/GraphObject.html#visible" class="linkProperty">visible</a>,or by setting <a href="../symbols/GraphObject.html#opacity" class="linkProperty">opacity</a> to zero if you still want the GraphObject to occupy space.Also, if you want to control whether any mouse or touch events "see" the GraphObject,you can set <a href="../symbols/GraphObject.html#pickable" class="linkProperty">pickable</a> to false.<p>For more information about specifying how things get drawn, see the properties on the<a href="../symbols/Shape.html" class="linkConstructor">Shape</a>, <a href="../symbols/TextBlock.html" class="linkConstructor">TextBlock</a>, and <a href="../symbols/Picture.html" class="linkConstructor">Picture</a> classes.<h3>GraphObject Sizing</h3><p>GraphObject defines most of the properties that cause objects to size themselves differently.The most prominent ones include:<ul><li>The <a href="../symbols/GraphObject.html#desiredSize" class="linkProperty">desiredSize</a>, <a href="../symbols/GraphObject.html#minSize" class="linkProperty">minSize</a>, and <a href="../symbols/GraphObject.html#maxSize" class="linkProperty">maxSize</a> properties are used toexplicitly set or limit the size of visual elements. <a href="../symbols/GraphObject.html#width" class="linkProperty">width</a> and <a href="../symbols/GraphObject.html#height" class="linkProperty">height</a> areconvenience properties that set the <a href="../symbols/GraphObject.html#desiredSize" class="linkProperty">desiredSize</a> width and height, respectively.</li><li>The <a href="../symbols/GraphObject.html#angle" class="linkProperty">angle</a> and <a href="../symbols/GraphObject.html#scale" class="linkProperty">scale</a> properties are used to transform visual elements.</li><li>The <a href="../symbols/GraphObject.html#stretch" class="linkProperty">stretch</a> property determines how a GraphObject will fill its visual space,contextually granted to it by its containing <a href="../symbols/Panel.html" class="linkConstructor">Panel</a>. Top-level (<a href="../symbols/Part.html" class="linkConstructor">Part</a>)GraphObjects are not affected by this property because they are always granted infinite space.</li></ul><p>All GraphObjects in a Diagram are measured and then arranged by their containing <a href="../symbols/Panel.html" class="linkConstructor">Panel</a>s in a tree-like fashion.After measuring and arranging, a GraphObject will have valid values for the read-onlyproperties <a href="../symbols/GraphObject.html#naturalBounds" class="linkProperty">naturalBounds</a>, <a href="../symbols/GraphObject.html#measuredBounds" class="linkProperty">measuredBounds</a>, and <a href="../symbols/GraphObject.html#actualBounds" class="linkProperty">actualBounds</a>.<p><ul><li>The <a href="../symbols/GraphObject.html#naturalBounds" class="linkProperty">naturalBounds</a> of a GraphObject describe its local size,without any transformations (<a href="../symbols/GraphObject.html#scale" class="linkProperty">scale</a>, <a href="../symbols/GraphObject.html#angle" class="linkProperty">angle</a>) affecting it.</li><li>The <a href="../symbols/GraphObject.html#measuredBounds" class="linkProperty">measuredBounds</a> of a GraphObject describe its size relative to its containing Panel.</li><li>The <a href="../symbols/GraphObject.html#actualBounds" class="linkProperty">actualBounds</a> of a GraphObject describe its position and given size inside of its panel.This size may be smaller than <a href="../symbols/GraphObject.html#measuredBounds" class="linkProperty">measuredBounds</a>, for instance if a GraphObject with a large <a href="../symbols/GraphObject.html#desiredSize" class="linkProperty">desiredSize</a>is placed in a <a href="../symbols/Panel.html" class="linkConstructor">Panel</a> of a smaller <a href="../symbols/GraphObject.html#desiredSize" class="linkProperty">desiredSize</a>. Smaller <a href="../symbols/GraphObject.html#actualBounds" class="linkProperty">actualBounds</a> than <a href="../symbols/GraphObject.html#measuredBounds" class="linkProperty">measuredBounds</a>typically means an object will be cropped.</li></ul><p class="boxread">See <a href="../../intro/sizing.html">the Introduction page on sizing</a>for usage information and examples.<h3>GraphObject Size and Position within Panel</h3>Several GraphObject properties guide the containing <a href="../symbols/Panel.html" class="linkConstructor">Panel</a> for how to size and position the object within the panel.<ul><li>The <a href="../symbols/GraphObject.html#alignment" class="linkProperty">alignment</a> specifies where the object should be relative to some area of the panel.For example, an alignment value of <a href="../symbols/Spot.html#BottomRight" class="linkConstant">Spot.BottomRight</a> means that the GraphObject should be at the bottom-right corner of the panel.</li><li>The <a href="../symbols/GraphObject.html#alignmentFocus" class="linkProperty">alignmentFocus</a> specifies precisely which point of the GraphObject should be aligned at the <a href="../symbols/GraphObject.html#alignment" class="linkProperty">alignment</a> spot.</li><li>The <a href="../symbols/GraphObject.html#column" class="linkProperty">column</a> and <a href="../symbols/GraphObject.html#row" class="linkProperty">row</a> properties are only used by <a href="../symbols/Panel.html#Table" class="linkConstant">Panel.Table</a> panels, to indicate where the GraphObject should be.</li><li>The <a href="../symbols/GraphObject.html#columnSpan" class="linkProperty">columnSpan</a> and <a href="../symbols/GraphObject.html#rowSpan" class="linkProperty">rowSpan</a> properties tell the <a href="../symbols/Panel.html#Table" class="linkConstant">Panel.Table</a> panel how large the GraphObject should be.</li><li>The <a href="../symbols/GraphObject.html#isPanelMain" class="linkProperty">isPanelMain</a> property indicates to some kinds of <a href="../symbols/Panel.html" class="linkConstructor">Panel</a>s that the GraphObject is the "primary" object that other panel children should be measured with or positioned in.</li><li>The <a href="../symbols/GraphObject.html#margin" class="linkProperty">margin</a> property tells the containing <a href="../symbols/Panel.html" class="linkConstructor">Panel</a> how much extra space to put around this GraphObject.</li><li>The <a href="../symbols/GraphObject.html#position" class="linkProperty">position</a> property is used to determine the relative position of GraphObjects when they are elements of a <a href="../symbols/Panel.html#Position" class="linkConstant">Panel.Position</a> panel.</li></ul><p class="boxread">See <a href="../../intro/panels.html">the Introduction page on Panels</a>and <a href="../../intro/tablePanels.html">Table Panels</a> for an overview of the capabilities.<h3>Top-level GraphObjects are Parts</h3><p>A <a href="../symbols/Part.html" class="linkConstructor">Part</a> is a derived class of GraphObject representing a top-level object.All top-level GraphObjects must be Parts, and Node, Link, Group, and Adornment derive from Part.The position of a Part determines the point of the Part's top-left corner in document coordinates.See also <a href="../symbols/Part.html#location" class="linkProperty">Part.location</a>, which supports an way to specify the position based on a differentspot of a different element within the Part.<p>There are several read-only properties that help navigate up the visual tree.<ul><li><a href="../symbols/GraphObject.html#panel" class="linkProperty">panel</a> returns the <a href="../symbols/Panel.html" class="linkConstructor">Panel</a> that directly contains this GraphObject</li><li><a href="../symbols/GraphObject.html#part" class="linkProperty">part</a> returns the <a href="../symbols/Part.html" class="linkConstructor">Part</a> that this GraphObject is in, perhaps via intervening Panels; this is frequently used in order to get to the model data, <a href="../symbols/Panel.html#data" class="linkProperty">Panel.data</a></li><li><a href="../symbols/GraphObject.html#layer" class="linkProperty">layer</a> returns the <a href="../symbols/Layer.html" class="linkConstructor">Layer</a> that this GraphObject's Part is in</li><li><a href="../symbols/GraphObject.html#diagram" class="linkProperty">diagram</a> returns the <a href="../symbols/Diagram.html" class="linkConstructor">Diagram</a> that this GraphObject's Part's Layer is in</li></ul><p class="boxrun">See <a href="../../samples/visualTree.html">the Visual Tree sample</a>for a diagram displaying the visual tree of a simple diagram.<h3>User Interaction</h3><p>GraphObjects have several properties enabling dynamic customizable interaction.There are several definable functions that execute on input events: <a href="../symbols/GraphObject.html#mouseDragEnter" class="linkProperty">mouseDragEnter</a>,<a href="../symbols/GraphObject.html#mouseDragLeave" class="linkProperty">mouseDragLeave</a>, <a href="../symbols/GraphObject.html#mouseDrop" class="linkProperty">mouseDrop</a>, <a href="../symbols/GraphObject.html#mouseEnter" class="linkProperty">mouseEnter</a>, <a href="../symbols/GraphObject.html#mouseHold" class="linkProperty">mouseHold</a>,<a href="../symbols/GraphObject.html#mouseHover" class="linkProperty">mouseHover</a>, <a href="../symbols/GraphObject.html#mouseLeave" class="linkProperty">mouseLeave</a>, and <a href="../symbols/GraphObject.html#mouseOver" class="linkProperty">mouseOver</a>.For example, you could define mouse enter-and-leave event handlers to modify the appearance of a linkas the mouse passes over it:<pre>myDiagram.linkTemplate =  $(go.Link,    $(go.Shape,      { strokeWidth: 2, stroke: "gray" },  // default color is "gray"      { // here E is the InputEvent and OBJ is this Shape        mouseEnter: function(e, obj) { obj.strokeWidth = 4; obj.stroke = "dodgerblue"; },        mouseLeave: function(e, obj) { obj.strokeWidth = 2; obj.stroke = "gray"; }      }));</pre><p>There are <a href="../symbols/GraphObject.html#click" class="linkProperty">click</a>, <a href="../symbols/GraphObject.html#doubleClick" class="linkProperty">doubleClick</a>, and <a href="../symbols/GraphObject.html#contextClick" class="linkProperty">contextClick</a> functionsthat execute when a user appropriately clicks the GraphObject.These click functions are called with the <a href="../symbols/InputEvent.html" class="linkConstructor">InputEvent</a> as the first argumentand this GraphObject as the second argument.For example, you could define a click event handler on a Node that goes to another page:<pre>myDiagram.nodeTemplate =  $(go.Node, "Auto",    $(go.Shape, "RoundedRectangle",      new go.Binding("fill", "color")),    $(go.TextBlock,      { name: "TB", margin: 3 },      new go.Binding("text", "key")),    { // second arg will be this GraphObject, which in this case is the Node itself:      click: function(e, node) {        window.open("https://en.wikipedia.org/Wiki/" + node.data.key);      }    });</pre><p>Note: you may prefer defining <a href="../symbols/DiagramEvent.html" class="linkConstructor">DiagramEvent</a> listeners on the <a href="../symbols/Diagram.html" class="linkConstructor">Diagram</a>rather than on individual GraphObjects.  DiagramEvents also include more general events thatdo not necessarily correspond to input events.<p>The properties <a href="../symbols/GraphObject.html#actionCancel" class="linkProperty">actionCancel</a>, <a href="../symbols/GraphObject.html#actionDown" class="linkProperty">actionDown</a>, <a href="../symbols/GraphObject.html#actionMove" class="linkProperty">actionMove</a>,and <a href="../symbols/GraphObject.html#actionUp" class="linkProperty">actionUp</a> define functions to execute when the GraphObject's <a href="../symbols/GraphObject.html#isActionable" class="linkProperty">isActionable</a> propertyis set to true (default false). See the <a href="../symbols/ActionTool.html" class="linkConstructor">ActionTool</a> for more detail.<p class="boxread">See <a href="../../intro/events.html">the Introduction page on Events</a> for a more general discussion.<h3>GraphObjects as Ports</h3><p>In GoJS, <a href="../symbols/Link.html" class="linkConstructor">Link</a>s can only connect to elements within a <a href="../symbols/Node.html" class="linkConstructor">Node</a>that are specified as "ports", and by default the only port is the Node itself.Setting the <a href="../symbols/GraphObject.html#portId" class="linkProperty">portId</a> of a GraphObject inside a Node allows that object to act as a port.Note: the only kind of model that can save which port a link is connected with, i.e. portIds that are not an empty string,is a <a href="../symbols/GraphLinksModel.html" class="linkConstructor">GraphLinksModel</a> whose <a href="../symbols/GraphLinksModel.html#linkFromPortIdProperty" class="linkProperty">GraphLinksModel.linkFromPortIdProperty</a> and<a href="../symbols/GraphLinksModel.html#linkToPortIdProperty" class="linkProperty">GraphLinksModel.linkToPortIdProperty</a> have been set to name properties on the link data objects.<p>GraphObjects have several properties that are only relevant when they are acting as ports.These port-related properties are:<ul><li><a href="../symbols/GraphObject.html#portId" class="linkProperty">portId</a>, which must be set to a string that is unique within the <a href="../symbols/Node.html" class="linkConstructor">Node</a>,    in order for this GraphObject to be treated as a "port", rather than the whole node</li><li><a href="../symbols/GraphObject.html#fromSpot" class="linkProperty">fromSpot</a> and <a href="../symbols/GraphObject.html#toSpot" class="linkProperty">toSpot</a>, where a link should connect with this port</li><li><a href="../symbols/GraphObject.html#fromEndSegmentLength" class="linkProperty">fromEndSegmentLength</a> and <a href="../symbols/GraphObject.html#toEndSegmentLength" class="linkProperty">toEndSegmentLength</a>, the length of the link segment adjacent to this port</li><li><a href="../symbols/GraphObject.html#fromEndSegmentDirection" class="linkProperty">fromEndSegmentDirection</a> and <a href="../symbols/GraphObject.html#toEndSegmentDirection" class="linkProperty">toEndSegmentDirection</a>, the orientation of the link when connecting to this port</li><li><a href="../symbols/GraphObject.html#fromShortLength" class="linkProperty">fromShortLength</a> and <a href="../symbols/GraphObject.html#toShortLength" class="linkProperty">toShortLength</a>, the distance the link should terminate before touching this port</li><li><a href="../symbols/GraphObject.html#fromLinkable" class="linkProperty">fromLinkable</a> and <a href="../symbols/GraphObject.html#toLinkable" class="linkProperty">toLinkable</a>, whether the user may draw links connecting with this port</li><li><a href="../symbols/GraphObject.html#fromLinkableDuplicates" class="linkProperty">fromLinkableDuplicates</a> and <a href="../symbols/GraphObject.html#toLinkableDuplicates" class="linkProperty">toLinkableDuplicates</a>, whether the user may draw multiple links between the same pair of ports</li><li><a href="../symbols/GraphObject.html#fromLinkableSelfNode" class="linkProperty">fromLinkableSelfNode</a> and <a href="../symbols/GraphObject.html#toLinkableSelfNode" class="linkProperty">toLinkableSelfNode</a>, whether the user may draw a link between ports on the same node</li><li><a href="../symbols/GraphObject.html#fromMaxLinks" class="linkProperty">fromMaxLinks</a> and <a href="../symbols/GraphObject.html#toMaxLinks" class="linkProperty">toMaxLinks</a>, to limit the number of links connecting with this port in a particular direction</li></ul><p class="boxread">See <a href="../../intro/ports.html">the Introduction page on ports</a>and <a href="../../intro/connectionPoints.html">link connection points</a>for port usage information and examples.<h3>GraphObjects as labels on a Link</h3><p>GraphObjects can also be used as "labels" on a <a href="../symbols/Link.html" class="linkConstructor">Link</a>.In addition to the <a href="../symbols/GraphObject.html#alignmentFocus" class="linkProperty">alignmentFocus</a> property, these properties direct a Link Panelto position a "label" at a particular point along the route of the link, in a particular manner:<ul><li><a href="../symbols/GraphObject.html#segmentIndex" class="linkProperty">segmentIndex</a>, which segment the label should be on</li><li><a href="../symbols/GraphObject.html#segmentFraction" class="linkProperty">segmentFraction</a>, how far along the segment the label should be</li><li><a href="../symbols/GraphObject.html#segmentOffset" class="linkProperty">segmentOffset</a>, where the label should be positioned relative to the segment</li><li><a href="../symbols/GraphObject.html#segmentOrientation" class="linkProperty">segmentOrientation</a>, how the label should be rotated relative to the angle of the segment</li></ul><p class="boxread">See <a href="../../intro/linkLabels.html">the Introduction page on link labels</a>for examples of how to make use of labels on Links.<h3>Interactive Behavior</h3><p>There are several properties that specify fairly high-level interactive behavior:<ul><li><a href="../symbols/GraphObject.html#cursor" class="linkProperty">cursor</a>, a CSS string specifying a cursor</li><li><a href="../symbols/GraphObject.html#contextMenu" class="linkProperty">contextMenu</a>, an <a href="../symbols/Adornment.html" class="linkConstructor">Adornment</a></li><li><a href="../symbols/GraphObject.html#toolTip" class="linkProperty">toolTip</a>, an <a href="../symbols/Adornment.html" class="linkConstructor">Adornment</a></li></ul><p class="boxread">For more information, please read <a href="../../intro/contextMenus.html">the Introduction page about Context Menus</a>and <a href="../../intro/toolTips.html">the page about ToolTips</a>.<p class="boxrun">Also see <a href="../../samples/basic.html">the Basic sample</a>for examples of how to show context menus and tooltips.

This can be implemented by showing an Adornment holding the buttons.<pre>var nodeContextMenu =  $(go.Adornment, "Spot",    { background: "transparent" },  // to help detect when the mouse leaves the area    $(go.Placeholder),    $(go.Panel, "Vertical",      { alignment: go.Spot.Right, alignmentFocus: go.Spot.Left },      $("Button",        $(go.TextBlock, "Command 1"),        {          click: function(e, obj) {            var node = obj.part.adornedPart;            alert("Command 1 on " + node.data.text);            node.removeAdornment("ContextMenuOver");          }        }),      $("Button",        $(go.TextBlock, "Command 2"),        {          click: function(e, obj) {            var node = obj.part.adornedPart;            alert("Command 2 on " + node.data.text);            node.removeAdornment("ContextMenuOver");          }        })      ));</pre>Then in the definition of the Node we can implement a mouseEnter event handler:<pre>myDiagram.nodeTemplate =  $(go.Node,    . . .    {      mouseEnter: function(e, node) {        nodeContextMenu.adornedObject = node;        nodeContextMenu.mouseLeave = function(ev, cm) {          node.removeAdornment("ContextMenuOver");        };        node.addAdornment("ContextMenuOver", nodeContextMenu);      }    });</pre>Note how it automatically defines a <a href="../symbols/GraphObject.html#mouseLeave" class="linkProperty">mouseLeave</a> event handler too.The context menu Adornment is removed either when the mouse leaves the area of the Adornmentor when the user executes a button click event handler.</div>

name of a predefined kind of Panel.This function will construct a new instance of that type and use the rest of the arguments to initialize the object.The first argument cannot be a regular Object (such as a GraphObject) that you are trying to initialize;for that you can call <a href="../symbols/GraphObject.html#setProperties" class="linkMethod">setProperties</a> or <a href="../symbols/Diagram.html#setProperties" class="linkMethod">Diagram.setProperties</a>, although that wouldbe less efficient than setting properties directly.<p>If an initializer argument is an enumerated value, this tries to set the property that seems most appropriate.<p>If an initializer argument is a string, this sets a particular property depending on the type of object being built.<ul><li>If the object is a <a href="../symbols/TextBlock.html" class="linkConstructor">TextBlock</a>, it sets <a href="../symbols/TextBlock.html#text" class="linkProperty">TextBlock.text</a>.</li><li>If the object is a <a href="../symbols/Shape.html" class="linkConstructor">Shape</a>, it sets <a href="../symbols/Shape.html#figure" class="linkProperty">Shape.figure</a>.</li><li>If the object is a <a href="../symbols/Picture.html" class="linkConstructor">Picture</a>, it sets <a href="../symbols/Picture.html#source" class="linkProperty">Picture.source</a>.</li><li>If the object is a <a href="../symbols/Panel.html" class="linkConstructor">Panel</a> (including <a href="../symbols/Part.html" class="linkConstructor">Part</a>, <a href="../symbols/Node.html" class="linkConstructor">Node</a>, or <a href="../symbols/Group.html" class="linkConstructor">Group</a>), it sets <a href="../symbols/Panel.html#type" class="linkProperty">Panel.type</a>.</li></ul><p>If an initializer argument is a particular kind of object, this can add that object to the object being built.<ul><li><a href="../symbols/GraphObject.html" class="linkConstructor">GraphObject</a>s and <a href="../symbols/RowColumnDefinition.html" class="linkConstructor">RowColumnDefinition</a>s can only be added as elements of <a href="../symbols/Panel.html" class="linkConstructor">Panel</a>s.</li><li><a href="../symbols/Binding.html" class="linkConstructor">Binding</a>s can only be applied to <a href="../symbols/GraphObject.html" class="linkConstructor">GraphObject</a>s and <a href="../symbols/RowColumnDefinition.html" class="linkConstructor">RowColumnDefinition</a>s.</li><li><a href="../symbols/PathFigure.html" class="linkConstructor">PathFigure</a>s can only be added to <a href="../symbols/Geometry.html" class="linkConstructor">Geometry</a> objects.</li><li><a href="../symbols/PathSegment.html" class="linkConstructor">PathSegment</a>s can only be added to <a href="../symbols/PathFigure.html" class="linkConstructor">PathFigure</a> objects.</li><li>Regular JavaScript Arrays provide a sequence of initializer arguments.</li><li>Regular JavaScript objects provide property/value pairs that are set on the object being built.</li></ul>When the initializer argument is a plain JavaScript Object, there are several ways that that object's properties are applied.If the property name is a string with a period inside it, this has a special meaning if the object is a <a href="../symbols/Panel.html" class="linkConstructor">Panel</a> or a <a href="../symbols/Diagram.html" class="linkConstructor">Diagram</a>.At the current time only a single period separator is valid syntax for a property string, and it is valid only on Panels and Diagrams.<p>For Panels, the substring before the period is used as the name passed to <a href="../symbols/Panel.html#findObject" class="linkMethod">Panel.findObject</a>to get the actual object on which to set the property, which is the substring after the period.This is normally useful only on the predefined Panels:<ul><li>a <b>"Button"</b> has a <a href="../symbols/Shape.html" class="linkConstructor">Shape</a> named "ButtonBorder" surrounding the content of the Panel.</li><li>a <b>"TreeExpanderButton"</b> has a "ButtonBorder" Shape and a "ButtonIcon" Shape that is the plus-or-minus sign.</li><li>a <b>"SubGraphExpanderButton"</b> has a "ButtonBorder" Shape and a "ButtonIcon" Shape that is the plus-or-minus sign.</li><li>a <b>"ContextMenuButton"</b> has a Shape named "ButtonBorder" surrounding the content of the Panel.</li></ul>But you can define your own names that GraphObject.make can build by calling the static function GraphObject#defineBuilder.<p>For Diagrams, the substring before the period is used as the name of a property on the Diagram itselfto get the actual object on which to set the property.As a special case, if such a property value does not exist on the Diagram, it looks on the <a href="../symbols/Diagram.html#toolManager" class="linkProperty">Diagram.toolManager</a>.See some examples below.<p>Also for Diagrams, and only for Diagrams, if the property name is the name of a <a href="../symbols/DiagramEvent.html" class="linkConstructor">DiagramEvent</a>,the property value must be a DiagramEvent listener function, and <a href="../symbols/Diagram.html#addDiagramListener" class="linkMethod">Diagram.addDiagramListener</a> is calledusing that DiagramEvent name and that function.Note that all DiagramEvent names are capitalized and do not contain any periods,so there cannot be any name conflicts with any properties on <a href="../symbols/Diagram.html" class="linkConstructor">Diagram</a> or <a href="../symbols/ToolManager.html" class="linkConstructor">ToolManager</a>.Although you can register multiple listeners for the same DiagramEvent names, due to JavaScript limitationsthose need to be declared using separate JavaScript objects, because JavaScript does not permit duplicate property namesin an Object literal.<p>Furthermore for Diagrams, if the property name is "Changed" or "ModelChanged",the property value must be a ChangedEvent listener function, which is called with a <a href="../symbols/ChangedEvent.html" class="linkConstructor">ChangedEvent</a> argument.When the property name is "Changed", it calls <a href="../symbols/Diagram.html#addChangedListener" class="linkMethod">Diagram.addChangedListener</a>,notifying about changes to the Diagram or its Layers or GraphObjects.When the property name is "ModelChanged", it calls <a href="../symbols/Model.html#addChangedListener" class="linkMethod">Model.addChangedListener</a> on the <a href="../symbols/Diagram.html#model" class="linkProperty">Diagram.model</a>,resulting in notifications about changes to the Model or its data.This is handy because the <a href="../symbols/Diagram.html#model" class="linkProperty">Diagram.model</a> property setter will automatically call<a href="../symbols/Model.html#removeChangedListener" class="linkMethod">Model.removeChangedListener</a> on the old model, thereby avoiding any overhead if there are anymore changes to the old model and also avoiding a reference to the listener which might cause garbage collection retention.It also will call <a href="../symbols/Model.html#addChangedListener" class="linkMethod">Model.addChangedListener</a> on the new model, helping implement the same behavior with the new model.<p>If the property name is a number and if the object being constructed is a <a href="../symbols/Brush.html" class="linkConstructor">Brush</a>,the number and value are added to the Brush by calling <a href="../symbols/Brush.html#addColorStop" class="linkMethod">Brush.addColorStop</a>.<p>Otherwise the property name is used as a regular property name on the object being built.This tries to do some property name and value checking:when a property is not defined on the object being built, it will signal an error.Many typos can be found this way that would be ignored by JavaScript code.<p>If the property name begins with an underscore, this will not complain about the property being undefined.Not only is that underscore property set on the object being built, but calls to <a href="../symbols/GraphObject.html#copy" class="linkMethod">copy</a>will also copy the values of such named properties to the new objects.<p>In the samples and in the intro pages this function is called using the alias "$".You can use a different short name if you would like to preserve the use of "$" for another JavaScript library.<pre> var $ = go.GraphObject.make; var diagram =
